Introducing G-TAP A-TX21
G-TAP A-TX21 is the first installment in a line of active TAPs from G-TAP A Series 2 , that are designed to eliminate network link downtime on network connections , monitoring link state and power state of connected devices, as well as, providing network security .This section introduces G-TAP A-TX21 with a detailed description on the features ,functions and an orientation to the physical layout of the TAP .
G-TAP A-TX21 Overview
The G-TAP A-TX21 is a line of active network TAP that mirrors 100% of network traffic, implements the “Always-On” architecture, has increased density, and improved security. The new G-TAP A-TX21 will function on GigaVUE-OS (X86 base) used by the GigaVUE H Series and can be managed in GigaVUE-FM.
A network TAP is a hardware component device that connects directly to the cabling infrastructure to split or copy packets of network to use in analysis,security or general network management. Active TAPs are a type of network TAP that require power source to regenerate signals.These TAPs provide visibility to sections of the network that would otherwise go unmonitored.
Active taps (G-TAP A-TX21) offer battery backup to extend usage of the TAP during power failures. During a power outage, an active TAP cannot regenerate the signal, so it becomes a point of failure. G-TAP A-TX21 incorporates bypasses to mitigate this issue. When the battery begins to die, the TAP will offer additional failover capabilities.
For example, when G-TAP A-TX21 loses power, electromagnetic relays fall into place to physically close a link to allow traffic to continue flowing through the network. The monitoring traffic stops, but at least the network traffic is protected. Do be aware that when the relay closes, a renegotiation takes place so a few packets would be affected
